ICE-CREAM FREEZER.

Application filed. January To @ZZ whom if' 71mg/ concern:

Be it known that l, iDnLAnD BOUCHER, a citizen of Canada, residing atVinchendon, in the county of lviorcester and State of Massachusetts,have invented certain new and useful improvements in ice-Cream Freezers,of which the following is a specification.

This invention relates to ice cream freez ers, the invention having` foran object to provide an improved and novel beate or agitatorl for thecream, having means applied thereto wiereby a compound beating actioncan be given the beater, which is pret erably made up of a number ofrelatively movable elements.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is an axial sectional view of an ice Cream freezerhaving the invention applied thereto.

Fig. 2 is a fragmentary axial sectional view at right angles to Fig. 1.

Referring now to the drawing, the reference numeral 10 indicates theouter receptacle of the freezer, and 11 the inner receptacle, the latterbeing of cylindrical shape, the freezer being provided with a cover 12.This cover is formed with an aperture to receive the upwardly projectingstem or trunnion 14 of the beater. rThis beater comprises a vertical bar15 that extends axially through the receptacle and is formed with alongitudinal slot 16 passing from side to side thereof and extendingsubstantially the full length thereof. 1n this bar are mounted a seriesof beater elements comprising a ring 18 that is positioned substantiallymidway between top and bottoni ends of the bar, and a pair of semi-rings19 and 19 that are positioned one above and one below the cen` tralringl 18. rllhese beater elements are arranged to have a slight rockingmovement imparted thereto, being rotatably supported by pins 22 passingthrough the diainetric elements 19b of the semi-rings, and a crosspiece18b on the ring 18, the ends of these pins being fined in the said bar15. rllhese members 18, 19, 19 are connected to one another to be rockedin unison by suitable 19, 1925.

means such as the teeth 24 ou the ring 18 engaging in notches -.5 in thesemisrings.

rihe top trunnion 14 of the beater bar 15 entends upward through and issupported by, a frame element 28 to the underside of which the cover 12is fixed, while the lower trunnion 14 of the beater bar is engagedfreely in a suitable socket 29 .in the bottom of the receptacle 11. Uponthe end of the top trunnion 14 is fixed a bevel gear 30 that isengigaged by a bevel pinion 31 on the inner end of a radially-extendinghorizontal shaft 82 supported by projections 28 from the frame 28, theshaf 82 having a crank handle on its outer end for turning purposes.

To impart a rocking movement to the va rions elements of the beater Iprovide a vertical plunger pin 86 that is slidably mounted in the frameelement 28 and is adapted to be engaged and pressed downwardly by meansof two cams 37 on the underside of the gear 30. The two cams arediametrically opposed to one another, being positioned in verticalalinement with the crosspiece 19b of the top beater element 19. The pinis urged upwardly by the coiled expansion spring 89 surrounding the pinin a socket 40 in the frame el-ement 28 and bearing upward on a collar41 fixed to the pin, upward movement of the latter being limited by thecollar 41 engaging a plug i2 fixed in the frame element 14.

1n the operation of my improved device, the cream is placed as usual inthe central receptacle 11, and the outer one is lilled with the usualsalt and ice mixture. When the handle is turned, the beater is rotated,and as the top element 19 thereon comes under the pin 36 the latter'comes under one of the cams 37 on the gear 30 and is depressed,imparting a slight rocking movement to all the beaters. When the beaterelement com- Vpletes another half revolution the pin 36 is cated oneabove and the other below the eentral ring, means for rotating saidshaft including a gear fixed tothe upper end thereof, a pair of cams onthe underside of said gear, and a plunger pin mounted in the said frameelement and adapted to be engaged by said cams to engage in turn the topbeater element to oseillate the latter.

2. In an iee cream freezer, a rotary beater, a frame element supportingsaid beater, said beater Comprising a longitudinally slotted Verticalshaft, a' series of skeleton beater elements supportedin said slot andconsisting,l of a central ring and a pair of se1ni-rings located oneabove and the other below the central ring, means for rotating saidshaft including a gear fixed to the upper end thereof, a pair of eanison the underside of said gear, and a plunger pin mounted in the saidfraine element and adapted to be engaged by said earns to engage in turnthe top beater element to os-V eillate the latter, and means effectingoperative connections between the Various beater elements whereby thelatter are eau-sed to osoillate in unison,

3. In an ice cream freezer, a rotary beater element comprising a.slotted bar, and a series of beaters supported in the slot in the saidbar and consisting of a centrally positioned ring and semi-rings onupper and lower sides thereof.

4. In an iee cream freezer, a rotary beater element comprising a slottedbar, and a series of beaters supported in the slot in the said bar andconsistingl of a centrally positioned ring and semi-rings on upper andlower sides thereof, means for rotating said bar, and means foroscillating the said beaters.

In testimony Ywhereof I have alixed my signature.
